Kansas City Chiefs star Rashee Rice appears to be in great spirits on his road to recovery ... hitting up the Jake Paul vs. Mike Tyson festivities in Texas as he inches closer to getting back on the football field.
After checking out the action at AT&T Stadium, the injured wide receiver rolled through the Rayleigh Underground in Dallas ... joining names like Metta World Peace, Jon Marianek and DJ Irie at the massive event's after-party.
Boxer J'Leon Love -- one of Paul's coaches -- was also present .
